June 8，from the Graduate School of Shandong University、Hosted by the Graduate Work Department of the Party Committee，The 11th (total 804) "Haiyou" Academic Forum hosted by the School of Electrical Engineering was held in the Power Building Hall of the Qianfoshan Campus as scheduled，This forum invited Xing Zezhi, a postgraduate student in 2019、Li Yahui as a guest speaker，Song Sili, Deputy Secretary of the Party Committee of the School of Electrical Engineering, Shandong University、Professor Li Kejun attended the forum as a guest as a guest，Sun Fengbin, the graduate school of the college。

At the beginning of the forum，The title of Xing Zezhi took the title "Research on the Key Basic Issues of Magic Magnetic Motor Electromagnetic Vibration"，From the basic situation of personal、Introduction to topic、The main results and summary of the main achievements and summary of the doctoral period are reported。He pointed out，At present, the electromagnetic vibration of the permanent magnet synchronous motor due to variable frequency power supply，Make the electromagnetic vibration problem increasingly complicated，Existing analysis methods have obvious shortcomings。So，During the doctoral period, he proposed that the sub-domain method and magnetic motility-magnetic waves combined with magnetic guidance method、The energy method -based stator inherent frequency and accurate calculation method and the use of linear superposition principles to obtain the vibration response of the stator under different frequencies of electromagnetic action to solve the problem of electromagnetic vibration，Get a series of outstanding results。

Li Yahui takes the title of "New Power System Diversified Drise Harmony and Modeling Analysis"，From the research background、Harmonic coupling generates characteristic analysis and modeling、Analysis of the characteristic analysis of diverse source loads and the construction of harmonic models、Harmony characteristics and influence analysis and summary and prospects to report。Li Yahui talks，Harmonic coupling，It is necessary to consider various types of equipment structure、Control difference，Multi -type harmonic analysis model of constructing form consistency。He is also from the abstract、Introduction and content to introduce the writing of papers and journals、Multi -angle comparison of conference papers and patents，Encourage students to lay a good foundation，Knowing difficulty and entering，Perseverance。

Li Kejun made a guiding suggestion on the classmates based on the report of the guest lecturer，He pointed out that he hoped that students were concentrated on scientific research、Do a good job of life、Society to face the setbacks in the scientific research process，"Get it as soon as possible"。Students who were present also asked the two brothers to ask the two brothers during the postgraduate period.，The two parties have conducted in -depth communication and interaction。

Song Sili made a summary comment。He pointed out that students must have a tough perseverance on the academic road，Young people must have the spirit of "asking for hard work"，Keep self -confidence，I hope more electrical students will be aligned with the guest speakers，Efforts to be an excellent researcher。

So far，This issue of "Haiyou" doctoral students academic forum is successfully concluded，Guests attended the stage to take a group photo。This "Haiyou" doctoral student exchange sharing forum provides a platform for students，Share through the academic research of outstanding doctoral students，Students in the Inspirational College adhere to the original intention of academic，persistent，Make outstanding contributions to the national power industry。
